Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hydraulic power unit suitable for use in homes and the like.

[Prior Art] Conventionally, in homes and the like, tap water supplied through water pipes connected to a water source is used as drinking water or washing water.

[Problem to be solved by the invention] However, the water pressure of tap water is generally 5 to 6 kg.
/cm2 is commonly used as the normal pressure, but it drops to about 0.5 kg/cm2 during active social activities during the day, for example. This drop in water pressure becomes more pronounced as you move up the floors of high-rise buildings, and water conditions worsen.

In addition, although there is a desire to develop energy sources that can replace electricity as a power source for various devices used in homes,
Since the water pressure of tap water fluctuates toward the low pressure side as described above, it is inconvenient to use it as a stable energy source.

An object of the present invention is to enable tap water to be used in a high-pressure state.

[Means for Solving the Problems] The hydraulic power unit of the present invention includes a pressure storage container that can store tap water in a pressure storage state, a water supply pipe that pressure-feeds the tap water to the pressure storage container, and a timely discharge of high-pressure stored water in the pressure storage container. It has a water outlet piping for making the water flow.

[Function] According to the present invention, tap water is pressurized by, for example, the pressurizing force of the tap water pressure in a normal pressure state or the pressurizing force of a water supply pump, and is fed under pressure through a water supply pipe and stored at a high pressure in a pressure accumulating container. Ru. As a result, the high-pressure water stored in the pressure storage container is discharged from the water outlet piping at an appropriate time, and can be used in a high-pressure state.

[Example] Fig. 1 is a piping diagram showing an example of the present invention, Fig. 2 is a schematic diagram showing an example of a pressure accumulator vessel, Fig. 3 is a schematic diagram showing constituent elements of the pressure accumulator vessel, and Fig. 4 is a schematic diagram showing an example of a pressure accumulator vessel. FIG. 5 is a diagram showing the relationship between the amount of water in the pressure storage container and the water pressure, and is a schematic diagram showing another example of the pressure storage container.

The hydraulic power unit 10 includes a pressure storage container 11, a water supply pipe 12, and a water output pipe 13.

The pressure storage container 11 is installed inside and outside the building, on the roof of the building, etc., and can store tap water in a pressure-accumulated state.

The water supply pipe 12 communicates with the pressure storage container 11, and feeds tap water under pressure to the pressure storage container 11. A water pipe 15 is connected to the water supply pipe 12 via a check valve 14, and the water pressure of the tap water supplied to the water pipe 15 allows this tap water to be pumped into the pressure accumulating container 11.

Further, a pressurizing pipe 16 is connected to the water supply pipe 12, bypassing the check valve 14 and continuing to the water pipe 15. The pressurizing pipe 16 is equipped with a water supply pump 17 and a check valve 18, and is capable of pressurizing the tap water in the water pipe 15 to a level higher than its normal pressure, so that this pressurized tap water can be force-fed to the pressure storage container 11 through the water supply pipe 12.

19 is a pump drive motor, and 20 is a pressure regulating valve that adjusts the degree of pressurization of tap water by the pump 17.

In addition, a pressure switch 21 is provided in the water supply pipe 12, and when the internal pressure of the pressure storage container 11 reaches a predetermined pressure,
This pressure switch 21 is activated to stop the pump 17 from pumping. Further, if the internal pressure of the pressure accumulating container 11 drops below the specified pressure when water is discharged, the pressure switch 21 is activated and the pump 17 resumes pressure feeding.

The water outlet pipe 13 extends from the pressure storage container 11 to the water-using equipment inside and outside the building, and is equipped with a stop valve 22. By opening and closing the stop valve 22, the high-pressure water stored in the pressure storage container 11 is released to the water-using equipment at a timely manner. urge Note that a water distribution joint to which water usage equipment is connected is provided at the terminal of the water outlet pipe 13.

The hydraulic power unit 10 operates as follows.

(2) When the water pressure of the water pipe 15 is greater than the internal pressure of the pressure accumulating container 11, the tap water is pressurized by the pressure of this water pressure, and the water supply pipe 12 is accumulated and stored in the mechanical pressure accumulating container 11.

(2) When accumulating pressure in the pressure accumulating container 11 at a pressure higher than the tap water pressure, the tap water is pressurized by the pressurizing force of the water supply pump 17, and is accumulated and stored in the pressure accumulating vessel 11 via the water supply pipe 12.

■The high-pressure water stored in the pressure storage container 11 is prevented from flowing back into the water pipe 15 by the check valves 14 and 18, and is prevented from flowing into the water outlet pipe 13 by closing the stop valve 22, resulting in the regulation of the pressure storage container 11. Pressure is maintained.

(2) When the stop valve 22 is opened, the high-pressure water stored in the pressure storage container 11 is sent from the water outlet pipe 13 to a desired water usage facility and used.

The high-pressure water of the water-pressure power unit 10 can be widely used to supplement when water pressure drops, to wash cars, wash windows, or sprinkle water with high-pressure water, or as a substitute when water is cut off.

Further, the high-pressure water of the hydraulic power unit 10 can be widely used as a stable high-pressure energy source for household automatic equipment such as a pickle making machine, a garbage dehydrator, an automatic door opening device, and the like.

In addition, the pressure storage container 11 of the hydraulic power unit 1o is as follows:
For example, it is composed of a spherical tank as shown in FIG.

The spherical tank is made by welding together the regular hexagonal plate 11A shown in Figure 3 and the regular pentagonal plate 11B as shown in Figure 2(A), and then applying internal pressure as shown in Figure 2(B). By expanding it into a spherical shape! I! It will be built. In addition, the second
The spherical tank with diameter D=50011II11 in the figure has a plate thickness of 3.2 mm and a side length a=100 mm (a=0.
20 sides of 2dl regular hexagonal plate 11A, plate thickness 3.2++
m, - side length a = 100mm (a = o, 2d)
This is an example in which 12 sides of regular pentagonal plates 11B are welded together and expanded into a perfect sphere with a diameter of 500 cm by applying an internal pressure of 80 kg/am2.

Table 1 and FIG. 4 show the relationship between water volume, liquid level, and water pressure when the above-mentioned spherical tank is used.

Note that the pressure accumulator 11 of the hydraulic power unit 10 is not limited to the spherical tank formed by the combination of the plates 11A and IIB, but may also be two hemispherical tanks formed by opposed hydraulic drawing or the like, as shown in FIG. It is also possible to use one constructed by butting the halves 11C111D and welding the seam.

Next, the operation of the above embodiment will be explained.

According to the above embodiment, the tap water is pressurized by the pressurizing force of the tap water pressure in the normal pressure state or the pressurizing force of the water supply pump 17, and is sent through the water supply pipe 12 and stored in the pressure accumulator container 11 at a high pressure. Ru.

As a result, the high-pressure water stored in the pressure storage container 11 is discharged from the water outlet pipe 13 at an appropriate time, and is made available under high pressure.

That is, the water pressure power unit 10 can easily generate high-pressure water at home or the like with a simple equipment configuration, and can use this water at desired water-using equipment inside or outside the building.

Therefore, rational use of water-using equipment such as household automatic equipment can be promoted.

In addition, in carrying out the present invention, the pressure accumulation container is not limited to a spherical tank, but a pressure accumulation cylinder or the like may also be used.

[Effects of the Invention] As described above, according to the present invention, the water pressure of tap water can be used in a high pressure state.
